Prof. Thierry Djenizian from Ecole Nationale Supérieure des Mines de Saint-Etienne and Aix-Marseille University, France, and Prof. Yury Gogotsi from Drexel University, USA, reported a novel porous materials as negative electrode for batteries and reported their work on ACS Applied Materials & Interfaces.
Li-ion batteries are the most studied and widely used energy storage devices for applications ranging from microelectronics to electric vehicles. To improve the electrochemical characteristics of LIBs beyond the current state-of-the-art, it is necessary to develop new electrode and electrolyte materials that can provide better performance with a smaller environmental footprint as possible and improved safety.
Prof. Djenizian and Prof. Gogotsi reported the synthesis of new porous materials obtained by anodization of MAX phases (Ti3SiC2) that can be used as negative electrode for microbatteries. The nanostructured anodes show very promising results in terms of specific capacity values, capacity retention, cycle ability, and coulombic efficiency.
